Unity3D教程宝典之两步实现超实用的XML存档

两步实现超实用的XML存档

本套存档的优点：易使用，跨平台，防作弊（内容加密 + 防拷贝）

脚本下载地址

使用方法非常简单：

把GameDataManager和XmlSaver两个脚本添加至工程后

(1)新建一个GameObject,起名GameDataManager并将GameDataManager脚本拖到上面。

(2)在GameDataManager里的GameData类中添加需要储存的数据

OK，跨平台防破解防拷贝的存档就搞定了！之后每次存档调用GameDataManager的Save函数，读档调用GameDataManager的Load函数。每次启动后GameDataManager会自动调用Load读档。如果玩家拿外来存档来覆盖本地存档，则游戏启动后数据清零，任何一次存档后作弊档被自动覆盖。注意：请勿放入二维以上数组，一般一维数据，枚举，自定义类等等数据类型可放心添加。





PS:风宇冲自己的U3d单机游戏和公司的单机游戏都用的这个XML存档,iOS,Android,PC,MAC都使用过的。放心使用吧。密钥的设定根据平台而定。
